Kai's verdictB-tier. Solid for autocomplete but the category moved past it. Pick Cursor unless you can't.S-tier for builders. The right primitives. What Kai is built on under the hood.S-tier if you live in the terminal. Different shape than Cursor — complementary, not replacement.A-tier for creators training custom looks. B-tier for general use.
